Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617244, here are decompositions:

7 + 8617237 = 8617244
37 + 8617207 = 8617244
43 + 8617201 = 8617244
67 + 8617177 = 8617244
73 + 8617171 = 8617244
331 + 8616913 = 8617244
463 + 8616781 = 8617244
487 + 8616757 = 8617244

Showing the first eight; more decompositions exist.
